TO WOM IT MAY CONCERN: f

Be it known that IMOB.RIS MATTSOX, of New York, in the county of New. York, andStnte of YNew York, have invented certain new and useful Improvements in Syringes; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings.

This invention is intended to supersede the necessity and avoid the objections of a. exible inlet tube in that class of syringes known as elastic bulb syringes, and to provide at the same time a means by which the hand and arm may be supported during the operation of administering any enema, no matter whatmay be the depth of the vessel in which the liquid is contained. To this end it consists in the combination, with the elastic bulb or chamber and flexible discharge tube, of a rigid inlet tube constructed in sections, so that its length may be increased or lessened, as desired, to adapt it to use with a deep or shallow vessel, and so that the syringe may b e lconveniently packed in small compass.

In order that others may understand fully the nature of my invention, I will proceed to describe it v'by reference to the accompanying drawings, in which- I Figure 1 is a side view of a syringe with a rigid inlet tube. g

Figure 2 is a vertical longitudinal section of my improved syringe, showing all the parts in operatingposition.

Figure 3 is a side view of thesupplernentary inlet tube detached from the other parts of the syringe.

General Description.

A is the elastic bulb of the syringe, constructed in accordance with certain reissued Letters Patent of the UnitedStates, granted to me for improvements in enema. syringes, and bearing date the eighteenth day of 'October, one thousand eight hundred and sixty-four, to which reference may be had for the details of construction of certain parts not herein so minntely described. B is the main inlet tube, which is' rigid,`and which is always attached to the other parts, represented in iig. 1, when the syringe is in use. .The aperture through it is made conical at the lower end to receive the auxiliary inlet tube or section C asrepresented in fig. 2; the upper end of said tube being made correspondingly conical to make it iit accurately, 'and also readily removed and replaced; Each of the sections B and C are scalloped at the lower end to admit the fluid while resting on the bottom of the vessel. D is a ilexible tube, made of India rubber, or its equivalent, to which the injection pipe Eis attached; the tube I) being connected to the main pipe, which extends from the bulb A, by a short branch pipe, F; said pipe, F, being connected between the induction valve and the bulb A.

Operation. When a deep vessel is used the tube C is attached, as represented in iig. 2, and the whole is used in precisely the same manner as the remaining parts, after dispensing with the auxiliary tube, would be used in a shallow vessel.

y CZaz'm. The application and use in syringes having an elastic bulb or air-chamber, and a iiexible discharge pipe, of

a rigid inexible inlet or suction tube or pipe, to serve as a rest or support for theA hand, when such inlet tube is constructed in sections as descrilrled,` so as to allow of being extended or contracted in length, substantially as and for the purposes set forth.

MORRIS MATTSON.
